CROSS REFERENCE TO RELATED APPLICATIONS

This application is a continuation of U.S. patent application Ser. No. 11/379,159 (set for issue as U.S. Pat. No. 8,016,151 on Sep. 13, 2011), entitled FLUID CONTROLLED CONTAINMENT BERM SYSTEM, filed Apr. 18, 2006, and incorporated herein in its entirety by this reference.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates generally to hazardous spill containment berms and more specifically it relates to a fluid controlled containment berm system for automatically forming a containment berm to contain hazardous liquid spills involving a vehicle.

2. Description of the Related Art

Any discussion of the prior art throughout the specification should in no way be considered as an admission that such prior art is widely known or forms part of common general knowledge in the field.

Conventional hazardous material containment berms are typically comprised of a solid concrete pit that the vehicle drives into for loading/unloading of hazardous materials such as chemicals, fuel and the like. Recently, portable hazardous material containment berms have been created that can be transported and setup in remote locations as desired. Conventional portable containment berms are comprised of a fabric attached to a supporting structure. These berms receive vehicles of various weights, sizes and lengths.

A main problem with conventional portable containment berms is that they require significant amounts of time and workers to assemble. A further problem with conventional portable containment berms is that they are relatively large in size and do not allow for a compact storage size. Another of the problems with conventional portable containment berms is that the corners of the fabric material are susceptible to tearing when driven over by the vehicle.

While conventional containment berms may be suitable for the particular purpose to which they address, they are not as suitable for automatically forming a containment berm to contain hazardous liquid spills involving a vehicle. Conventional containment berms typically require extensive setup time to create the supporting walls.

In these respects, the fluid controlled containment berm system according to the present invention substantially departs from the conventional concepts and designs of the prior art, and in so doing provides an apparatus primarily developed for the purpose of automatically forming a containment berm to contain hazardous liquid spills involving a vehicle.

B. Liner

The liner 20 has a floor 22 and at least one sidewall 24 as best illustrated in FIGS. 1 and 2 of the drawings. The liner 20 includes an inner surface and an outer surface, wherein the inner surface is adjacent to the liquid when being filled.

The liner 20 is preferably comprised of a flexible material to allow the present invention to be folded into a compact storage position as shown in FIGS. 6 a and 6 b of the drawings. The liner 20 may be comprised of various materials that are commonly utilized within the hazardous material containment industry that are non-permeably resistant to various chemicals and elements. The liner 20 preferably has an elongate shape with rounded end portions as illustrated FIGS. 1 and 2 of the drawings, however various other shapes may be utilized with the present invention. The liner 20 has a size sufficient for receiving various sizes of vehicles 12 and retaining various volumes of hazardous materials.

As best illustrated in 3 of the drawings, the sidewall 24 preferably has an angled or a curved structure that extends inwardly to contain the liquid within. When the sidewall 24 is angled (or curved) inwardly, the buoyant member 50 is elevated by the liquid entering the liner 20 and the liner 20 is prevented from over expanding which could result in spillage.

A pair of side members 70 preferably are attached to opposing portions of the liner 20 that is substantially parallel to the imaginary line X as shown in FIG. 1 of the drawings. The side members 70 preferably include a plurality of grommets 72 that receive a corresponding plurality of spikes 14 to secure the present invention to a surface.

As shown in FIG. 4 of the drawings, a pair of elongate pad members 16 are preferably positionable upon the end portions and the floor 22 of the liner 20 that a vehicle 12 drives upon. The pad members 16 60 protect the liner 20 from damage when the vehicle 12 drives upon the present invention.

C. Buoyant Member

A buoyant member 50 is attached to an upper portion of the liner 20 as best illustrated in FIGS. 1 and 2 of the drawings. The buoyant member 50 is comprised of a structure that is buoyant with hazardous liquids positioned within the interior of the liner 20. The buoyant member 50 is preferably comprised of at least one piece of resilient foam, however various other types of buoyant materials and buoyant structures may be utilized to form the buoyant member 50. The buoyant member 50 is preferably comprised of a resilient) buoyant foam material that is capable of lifting and elevating the upper portion of the liner 20 when a liquid is entered into the interior of the liner 20. The foam material is also preferably capable of being driven upon by heavy vehicles 12 without damage to the buoyant member 50. The buoyant member 50 preferably has a diameter of between 2 inches to 6 inches, but the diameter may be larger or smaller.

The buoyant member 50 preferably extends around all or at least a substantial portion of an inner perimeter of the liner 20 (i.e. the upper opening of the liner 20). The buoyant member 50 may be attached to the liner 20 in various manners such as within a tubular formation of the upper end of the liner 20 as shown in FIG. 3 of the drawings.

D. Reinforcing Members

A plurality of reinforcing members 40 are preferably attached to or within the sidewall 24 to assist in maintaining the integrity and shape of the sidewall 24 when the liner 20 is filled with liquid. The reinforcing members 40 are comprised of a substantially rigid material such as but not limited to fiberglass, metal or wood.

As shown in FIGS. 1 and 2 of the drawings, the plurality of reinforcing members 40 are preferably substantially parallel to one another. A plurality of pockets 30 are preferably attached to the sidewall 24 as shown in FIGS. 1 and 2 of the drawings. The plurality of pockets 30 retain each of the plurality of reinforcing members 40 as further shown in FIGS. 1 and 2 of the drawings. The pockets 30 may be comprised of an open structure or a closed structure. As further shown in FIG. 1 of the drawings, the plurality of reinforcing members 40 are preferably positioned within a pair of opposing elongated portions of the liner 20 with the reinforcing members 40 substantially transverse with respect to an imaginary line X extending along a longitudinal axis of the liner 20.

E. Diffuser Members

A pair of diffuser members 60 are attached between the floor 22 and the sidewall 24 as illustrated in FIGS. 1 through 3 of the drawings. The pair of diffuser members 60 are preferably substantially parallel to one another and approximately equal in length. The diffuser members 60 are preferably shorter than the sidewall 24. The diffuser members 60 are preferably comprised of elongated structures that extend substantially parallel with respect to the imaginary line X as shown in FIG. 1 of the drawings. The diffuser members 60 further ensure that the sidewall 24 keeps an inwardly curved and/or angle ensuring maximum containment of liquid. The diffuser members 60 each preferably are comprised of an elongated rectangular structure when expanded as best shown in FIG. 2 of the drawings.

The pair of diffuser members 60 are preferably attached to the liner 20 adjacent to the buoyant member 50 as shown in FIG. 3 of the drawings. Attachment of the diffuser members 60 adjacent to the buoyant member 50 prevents the buoyant member 50 from extending outwardly when filled with a liquid.

The pair of diffuser members 60 are preferably comprised of a porous material which diffuses a substantial flow of liquid in the event of a catastrophic event. The pair of diffuser members 60 are preferably comprised of a mesh material or other material that includes a plurality of apertures to allow liquid to flow through.

The pair of diffuser members 60 are each attached to the floor 22 of the liner 20 inwardly away of the sidewall 24 as best illustrated in FIG. 3 of the drawings. The pair of diffuser members 60 each preferably retain a portion of the sidewall 24 at an acute angle with respect to the floor 22 of the liner 20 when filled with a liquid as further shown in FIG. 3 of the drawings.

F. Operation of Invention

In use, the user positions the liner 20 in the desired location where the loading/unloading of hazardous materials is to take place as shown in FIGS. 1 and 4 of the drawings. The user thereafter is able to drive a vehicle 12 onto the floor 22 of the liner 20 as illustrated in FIGS. 5 a through 5 c of the drawings. The user drives across one of the ends of the liner 20 preferably upon the pad members 16 as the liner 20 is substantially flat at the end portions. The driver may drive the vehicle 12 across various other locations upon the liner 20 since the entire liner 20 is flat when in the non-filled flat state. The user continues to drive the vehicle 12 on the present invention until fully positioned within the liner 20 as shown in FIG. 5 c of the drawings. If a hazardous liquid is spilled into the liner 20, the hazardous liquid will first flood the floor 22 of the liner 20. The hazardous liquid will thereafter rise to a level adjacent to the sidewall 24 of the liner 20 and the buoyant member 50 wherein the liner 20 retains the liquid internally along with the buoyant member 50 rising slightly as shown in FIG. 5 d of the drawings. As the liquid further fills the interior of the liner 20, the buoyant member 50 continues to rise to an elevated state which correspondingly elevates the liner 20 as shown in FIG. 5 e of the drawings. The buoyancy of the buoyant member 50 is sufficient to elevate the liner 20 to ensure containment of the liquid within the interior of the liner 20 as shown in FIGS. 2, 3 and 5 e of the drawings. The user is thereafter able to cleanup the site by first recovering the hazardous liquid from within the liner 20 and thereafter cleaning the liner 20 for reuse at a later time. For storage, the present invention is simply folded into a compact storage position as shown in FIGS. 6 a and 6 b of the drawings.
